Abstract
The coupled boundary-value problem of nonstationary heat and mass transfer within the outer thermal insulation layer and the vapor outlet channel of a combined radiative-evaporative thermal protection system is formulated. The overall dimensional and weight characteristics of the system are calculated for a set of its parameters and two specified modes of the external heat flux and pressure variation, schematically modeling hypersonic aircraft flights 30 min and 60 min long with a maximum heat flux of 105 W/m2. Combined and passive radiative thermal protection systems are compared under the above-mentioned external conditions. It is shown that both the thickness of the outer thermal insulation layer and the total weight of the combined thermal protection system may be considerably less than the passive equivalents.
